PRESSURE-REGULATOR.

SPECIFICATION forming part of Letters Patent No.37,232, dated J`u1y261887.

I Application filed March 16, 1887. Serial No. 231,118. (No model.)

.To all whom, it may concern: Y

Be it known that I, GALE'N W. PEAEsoNs, a

citizen ofthe United States, residing at Kansas City, in the county ofJackson and State of Missouri, have invented certain new and usefulImprovements in Pressure-Regulators,

juxtapositon and in communication with the i pipes leading from the mainor other source of supply, the wall or walls of said chamber beingmadevflexible, and connected to a valve which will close the circuit andshut oft' the flow when the walls of the chamber are distended by thepressure ofthe water, gas, or

steam within the chamber.

In the drawing, which is a vertical longif tudinal section through thecenter of the device, A indicates the pressure-chamber,which may be ofany suitable or desirable shape, made in two parts, and the two partsprovided at the outer edge with inwardly-proj ecting flanges a', and atthe center with bosses a2 Vintegral therewith, and through the ribswhich abut, the parts are joined together bybolts or screws a, with anysuitable packing material interposed between the two sections, so as toform a tight joint. The walls B and Bl of the chamber are made elastic,so that they will be slightlybulged or distended when subjected tointernal pressure, but'will assume their normal position when thepressure is removed.

C is a T-couplingsecured to the wall B', to which are secured the inletand outlet pipes D and "E, respectively. The coupling C is provided witha valve-seat, b, in which is seated the valve c, said valve beingconnected to a stem, d, which passes through the cham ber A, and issecured in or to the wall B by means of the screw-threaded portion e andscrew-nut f, or in any other suitable manner. The opening in the lowerend of the T-coupling C is made larger than the stem of the valve, sothat when the pressure of the liquid,

steam, or gas in the pipe E becomes too great 'it will'escape into thechamber A, distending the walls thereof, which draws the valve c downonto the valve-seat b, and thus cut off 'the supply from the pipeD. Whenthe pressure has been released or exhausted ,from the pipe E, the wallsof the chamber gradually collapse, forcing a portion of the contents ofthe chamber out throughthe opening around the stem d into the pipe E andlifting` the valve c from the seat b and placing the pipes D and E incommunication again.

The narrow opening around the stem dpermits the contents of the chamberto escape without causing a vibrating or iiattening action of the sidesof the chamber, as is the case with Inost of the devices of this classnow in use.v

It will be noticed that the suppl y-pipe and also the exhaust-pipe arelocated outside of the chamber, so that all the water, steam, or gasdoes not have to pass through the chamber, and that the chamber ispartially filled at all times with water, gas, 85e., thus renden ing thedevice extremely sensitive to variable pressure and causing it to actalmost instantly, insuring a reliable pressure-regulator.

Having thus described my invention,what I claim, and desire to secure byLetters Patent, 1s

1. In a device for regulating the flow of liquids or vapors, an elasticchamber comf posed of flexible disks with inwardly-projecting flangesand central bosses integral therewith bolted together, in combinationwith a valve-stem passing through one of said disks and adjustabl'ysecured to the other, and a valve located in a valve-chamber, and theinduction and eduction pipes connecting with said chamber, substantiallyas set forth.

2. The combination, with the disks B B', constructed and securedtogether substantially as described, of the coupling C, forming avalve-chamber,and provided with induction and eduction pipes, the valvec, valve-stem d, and nut f, substantially as and for the purpose setforth.

In testimony whereof I affix my signature in presence of two witnesses.
